I heard a similar point that this article makes a few years ago, but this is articulated much better.
Welcome to Socialism 101:
My New Spread the Wealth Grading Policy
by Mike S. Adams
Good afternoon students! I’m writing you this email to announce that I’m making some changes in the grading policies I announced two weeks ago when I sent an email with an attached course syllabus. As you know, we now have a new president and I thought it would be nice to align our class policies with some of the policies he will be implementing over the next four years. These will be changes you can believe in and, I hope, changes that will inspire hope, which is our most important American value.
Previously, I announced that I would use a ten-point grading scale, which means that 90% of 100 is an “A,” 80% is a “B,” 70% is a “C,” and 60% is enough for a passing grade of “D.” I also announced that I will refrain from using a “plus/minus” system – even though the faculty handbook gives me that option.
